eSIM Travel Tips for London
London is the most visited city for Australians in Europe
London is the most popular European destination for Australians. Qantas, British Airways, and many airlines fly direct from Sydney, Melbourne, Brisbane, and Perth to Heathrow. London is often the starting point for wider UK and Europe trips. Activate your HelloRoam UK eSIM at home before departure. One plan covers London and the rest of the UK.
The Elizabeth line has 4G throughout including tunnels
The Elizabeth line (Crossrail) is the best-connected line on the London Underground with 4G coverage throughout including all tunnel sections. This makes it far more connected than older deep Tube lines. The Elizabeth line runs from Heathrow Airport through central London to Shenfield and Abbey Wood.
Deep Tube lines lose signal in tunnels
Deep Tube lines including the Central, Northern, Jubilee, Victoria, and Piccadilly lines have 4G at platforms but lose signal in tunnels between stations. Download the TfL Oyster app and your maps before going underground on these lines. Coverage returns at each station.
The Oyster card app needs live data
The TfL Oyster and Contactless app for London Transport gives real-time journey planner results and balance updates. It works best with a live data connection. Install the app before your flight. You can also pay for the Tube and buses with contactless card or Google/Apple Pay directly.
Get the Santander Cycles app before exploring
London's Santander Cycles bike hire network is popular with tourists. The app shows real-time docking station availability and needs a live data connection. Your HelloRoam eSIM keeps it running as you cycle between attractions across central London.
Mobile networks in London: EE and Vodafone UK
London is served primarily by EE and Vodafone UK on 5G networks, along with Three and O2. EE runs London's most extensive 5G network across all Inner London boroughs and most of Outer London. Vodafone UK provides strong parallel 5G particularly in the West End, Mayfair, Canary Wharf, and major transport hubs. Your HelloRoam eSIM connects to EE and Vodafone UK for the broadest London coverage.

An eSIM activates instantly from Australia with no in-UK steps. | Telstra International Day Pass costs AU$10 per day in the UK. A two-week London and UK trip adds AU$140 in roaming charges.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
